UNITED STATES I PATENT OFFICE.

\VILLIAM B. DENITHORNE, OF PHCENIXVILLE, PENNSYLVANIA.

ROPE-CLAMP.

SPECIFICATION forming part of Letters Patent No. 361,932, dated April 26, 1887.

(No model.)

To all whom it may concern.-

Be it known that I, WILLIAM B. DENI- THORNE, a citizen of the United States, and a resident of Phoenixville, in the county of Chester and State of Pennsylvania, have invented certain new and'useful Improvements in Hope- Olamps; and'I do hereby declare that the following is a full, clear, and exact description of theinvention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure 1 is a perspective view of my invention. Fig. 2 is a vertical section through the rope-clamping plates. Fig. 3 is a side view of the device, one of the clamping-plates being removed. Fig. 4 is an edge of the clampingplate not shown in Fig. 3.

This invention relates to a device adapted to securely hold the end or other portion of a rope without requiring a knot to be formed or any considerable amount of winding of the rope.

In the drawings, A represents a plate carrying the device'and adapted to be secured to a post or other object where it is desired to use my invention. From this plate projects outward] y an arm, B, which I prefer to form with a double hook, b b, at the end, although it is not necessary to my invention that this arm should be hooked. Carried by this arm are two bow-shaped plates, 0 D, arranged with their convex faces toward'each other, and so connected as that one hasa rocking movement relatively to the other. The plate 0 is connected with and carried by the arm B and lies transverse thereto with its concave face toward the arm. Projecting from the central portion of convex face of plate 0 is a semicircular perforated plate or web, E, which enters and lies in a socket, F, in plate D. This socket is open for the reception of web E on the convex side of the plate, and has the two oppos. ing walls which form the sides of the socket perforated, as at f, so that when plate D is slipped over the web E these apertures f shall register with the aperture 6 in the web.

G is a pin which passes through the apertures f and e,and thus unitesthetwo clampingplates 0 and D, while at the same time permitting plate D to have a rocking movement to a limited extent relatively to the other plate around the web E.

I will now describe one position which the rope (indicated by H) may occupy when being held by the above-described device. The free end of the rope hangs down past the near side of arm B. Passing thence-over said arm and diagonally across the farther face thereof it lies between the lower diverging arms of plates 0 and D, and from there passes up and lies between the upper diverging arms of said plates, whence it may pass to any point desired. This is but one of many positions which the rope may occupy while being held by the clamp; but it will serve to illustrate the manner of use thereof.

It will be seen that any tension upon either end of the rope will tend to draw it more closely between the plates 0 and D toward their pivotal connection, and that such movement will force the opposite ends or arms of the plates toward each other, causing them to bind the rope at that point, thus preventing slipping,whatever be the strain upon the rope, for the more tightly the rope is drawn the more closely will it cause the arms of the plates to grip the portion of the rope lying between them.

This invention may be used for holding clothes-1i nes or wherever it is desired to stretch a rope from one place to another. It may also be advantageously used upon vessels in place of the ordinary cleats now employed.

That I claim is- In a rope-clamp, the combination of a base having an arm projecting therefrom, said arm having its outer end provided with hooks, a clamping-plate secured transversely upon said arm having a web, and a clampingplate having a recess pivotally secured upon said plate having the web.

In testimony thatlelaim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.
